SPECIFICATION forming part of Letters Patent No. '717,843, dated January 6, 1903. Application tiled October 28, 19O1.y Serial No. 80,261. (No model.)

To all whom iff/'may concer-7e:-

Be it known that I, JOSEPH A. GROEBLI, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new'and useful Improvements in-Embroidering Machinery, of`A whichv the following is a specification.

My invention relates to embroidering machinery, and has for its object to improve the construction of combined boring and piercing apparatus employed in such machines.

In United States Letters Patent No. 618,458, dated January 31, 1899, I have shown an embroidering machine structure wherein fare combined two sets of mechanisms for making holes in fabric stretched upon a tambourframe. These means are respectively a set of piercing bore-points having a cutting action and a set of rounded bore-points which serve to give shape to the holes made by the cutting borepoints. In the said patentV I have also shown means actuated and controiled from a jacquard mechanism by which either set of bore-points may be positioned for and thrown into action.

It sometimes occurs that in'cperating an embroidering-machine an'operator may not be on her guard or may be inattentive and may have her fingers wounded as the bore`4 points come into action with a quick.' motion.

In order to increase the protection for operaspeed-that is, during a period greater than one stitch period.

In the accompanying drawings I have shown one form of apparatus in which my invention is embodied. It will be understood, however, that this apparatus is shown by way of illustration merely and that my invention is not limited thereto. j

In the drawings, Figure 1 is an end view of the frame of an embroidering-machine, showing a structure embodying one form of my invention. Fig. 2 is a front elevation of the said mechanism. Fig. 3 is a front elevation, 'on an enlarged scale, of the parts at the upper left-hand side of Fig. 2. Fig. 4 is a side `'view thereof similar to the view shown in Fig. 1. Fig. 5 is a detail view of the actuating-gear; and Fig. 6 is an edge view of the said actuating-gear, partly' broken away.

In the drawings, 1 indicates the frame of the em broidering-macliine,which may be provided with'any desired form of fabric-frame, needle mechanism, and fabric-frame-moving mechanism. p

2 represents the jacquard or pattern mechanism, which for the purpose of the present :invention may be similar in character to the jacquard mechanism shown in United States Letters Patent No. 528,632, dated November 3is the main cam-shaft of the jacquard mechanism, with a suitable cam 4a carried thereby. The cam-shaft 3 makes one revolution for each stitch and carries a pinion 4, (most clearly shown in Fig. 5 of the drawings,) which pinion is adapted to mesh with a mu- At the' points 6 this slotted for the passage of movable teeth 7 8, which are carried upon a yoke 9, adapted to be oscillated by au arm 1 0, so as to project A"the tooth 8 or the tooth 'Las the case maybe, 'into engagement with the pinion 4.. A posivtioning-bar 11 is-pivoted to the gear 5 by its lower end and by its upper end to a settingvbar 12which is shown as toothed and meshing with pinions 13 14e.l The pinion 14 is carried on the shaft 15, which is connected to a rocking rail 16, carrying suitable'bore-points 17. The pinion 13 is carried upon a shaft 18,

connected to a suitable rocking rail 19, carrying bore-points 20. Rotation of the shafts 15 and 18 will cause the rails 1b and 19 to swing and bring their bore-points 17 and 20 into position for use. A cam L1a is mounted on the main shaft of the jacquard, and a bowl carried upon one end of a lever 22 operates in the cam-slot 21 therein. The lever 22 is pivoted at 23 and is pivotally connected to the lower end of an operating-bar 24, which is adapted to reciprocate the bore-points when the rail or IOO v ting-bar 12.

barcarryingthe bore-points has been rocked to set the bore-points. The bowl of the lever 22 is engaged with the cam at the appropriate time by suitable connections with the jacquard.l

(Not shown.) These connections may be of the construction shown in United States Letters Patent No. 618,458. The upper end of the operating-bar is slotted at 25 (see Fig. 3) andis provided with a connecting-pin 26, (see Fig. 4,) adapted for connection to or disconnection from the operating-arm 27 of the bore-point apparatus. This operating-arm 27 is secured to a rock-shaft 28 and is provided with a curved slot 29, in which the pin 26 is adapted to work. Beyond thelower end of the slot 29 a hole 3 0 is provided in a block 31, forming part of the operating-arm 27. A connecting-piece 32 is adjustably secured to the operating-arm andis apertured to receive the pin 26 when desired and is adjustable in order to change the initial positions of the apertures. The pin 26 is adapted to be shifted from the aperture in the connecting-piece to the aperture 30 in the operatingarm 27, which arm is swung by the setting and positioning mechanism, as will be described. A lever 33 (see Figs. 3 and 4) is pivoted on a stud 34 and is provided at its upper end with a finger 35, which enters the slot. 25 in theupper end of the operating-bar 24. The lower end of the pivoted lever 33 is provided with pins 36, which straddlea cam 37 on the set- The pinion 14 is provided with an arm 38, carrying a pin 39, which is adapt,- ed to Contact with an arm 40 on the army 27 to effect the raising of the end of the operating-arm and is also adapted to contact with an arm 27a on the adjustable piece 32 to lower the end of the operating-arm 27. In this manner the pin 39 eects the adjustment of the operating-arm in order to position the said arm so that the pin 26 can be entered either into the hole in the adjustable piece 32 or the hole 30 in the arm 27.

The gear 5 is provided with pins 4l, adapted to strike the free end of the lever 42, pivoted at 43 and provided with a link connection 44 to a bell 45, so that as the gear commences to rotate to position the bore-points the bell will be struck asia warning signal.

To the frame of the jacquard is secured a suitable cam 46, which is adapted during the movement of the gear 5 to move the yoke 9 to reposition the teeth 7 and 8 for the restoring operation.

The operation of the parts described is as follows: When the bore-points 2O are to be set in action, the jacquard mechanism is suitably actuated t cause the lifter 47 to be raised, thereby swinging the lever 10 on its pivot 48 and depressing the forked end thereof which embraces the pin 50, (or the pin 49,) and thereby forces the lower movable tooth 7 or Sinto engagement with the pinion 4. The motion of the pinion 4 is thus imparted to the gear 5 and rotation of the gear occurs, it being understood that as the gear rotates the pin The rotation of thegear Will cause the positioning-bar 11 to be drawn downward, thus moving the setting-bar 12 downward and rotating the pinions 13 and 14 to swing the rails 16 and 19 over to present the borepoints to the fabric. The downward movement ofthe setting-bar 12 will eect,through the agency of the cam 37, an outward swing of the lower end of the leverv 33. This will cause the upper end ofthe bar 24 to be swung inwardlythat is, inthe direction of the arrow in Fig. 3-and will withdraw the pin 26 from the aperture in the connecting-piege 32. As the pinion 14 rotates it brings the pin 39 carried thereby against the arm or abutment 40 on theoperatiug-'leven swinging the operating-lever upward untilY the aperture 30 comes opposite the pin 26 on the operatingbar 24, thus eecting a preliminary positioning of the bores. The upper end of the cam 37 now acts upon the lever 33 and causes the pin 26 to be entered into the hole 30. The eect of this movement ofthe operating-lever 27 is to draw the bore-points rearwardly into operating position, and as the jacquard enters the bowl of the lever 22 into the cam 21 on the jacquard-shaft the operating-bar 24, arm 2.7, andbore-points 2O aregiven an oscillating movement to effect the boring operation. The boring operation now continues until at a predetermined time (determined-by the jacquard) the parts are restored to their initial positions bya reverse movement, it

being understood thatin positioning the'parts the gear 5 makes a' half-revolution until'the space 6 is reached, when as the movable tooth 7 has been withdrawn as the tooth 8 was advancedl the gear 5 will stop, the tooth 8 striking against a stop 8a on the frame on thejacquard. During the movement of the gear the cam 46 operates to reset the yoke 9 and-to guide the pin 50 into the jaws 51 of bifurcated end of the lever 10.
